ABSTRACT:
A method of producing foil in a coil relates to the art of applying coatings under vacuum and can prove to be most advantageous in producing foil from pure metals. The proposed method is characterized in that the foil is obtained by continuous condensation of metallic vapors under vacuum on a layer of antiadhesive, said layer being applied to the surface of a rotating substrata, this resulting in producing a metal layer - the foil, and in forming simultaneously a coil thereof, both said operations: the producing of the foil and forming the coil thereof being effected on one rotating substrata so that each next metal layer is being formed on an antiadhesive layer applied to the preceding metal layer. With the herein-proposed method the produced foil exhibits the same degree of reflectivity from both sides, and it is also possible for a coil to be formed while producing the foil which ensures an adequate quality of said foil.
